Detecting Cut Points on Challenging Applications

One of principal issues of optical monitoring and control is the ability to handle cut points on difficult or noisy applications.  Making measurements when things are easy is by definition easy!  It gets more difficult when the nature of the actual measurement becomes less stable caused by the actual process parameters.  The following display has been created by an offline tool used at Telemark for testing the cut point algorithm offline.  Notice that the blue trace has some noise but ...

Affordable Broadband Optical Monitoring Tools

Telemark announces the NVision line of optical measurement tools for thin film coating monitoring and control. With over 25 years of history, these tools allow automatic control of optical properties during the deposition process. Real time, broadband optical monitoring and control systems measuring a single measurement point or up to one hundred monitoring locations provide evaluation and control of thin films during growth. This data is highly accurate and laboratory quality.
Each lab quality measurement location operates in real time ...

Low Stress, Densified Fluorides for IR Applications

Recent application work with infrared fluorides has demonstrated a significant advantage for IR applications. Using patented pulsing technology, the Telemark/Saintech ion sources have produced fully densified, index stable and stress control of fluoride compounds. These film properties can be achieved by deposition to unheated substrates. The study was performed in the Telemark applications lab and results were presented recently at the OIC conference in Whistler, Canada. Removal of inherent water peaks, index stabilization and fluoride dissociation has been a challenge ...

Telemark Value Engineered Water Vapor Cryotraps

Drawing on our leadership in the field of vacuum PVD coating, Telemark has released a new line of “value engineered” water vapor Cryotraps for PVD applications. To complement our existing line of TVP cryorefrigeration units, these “value engineered” systems support the necessity of water abatement in thin film PVD growth, while offering the lowest price per watt on the market. These systems eliminate the costly use of Ln2 and provide a fast payback for users.
Models include dual or single ...
